Interactive Decision Aids
2011
Decision support systems assist people in making a decision or choosing a course of action in a nonroutine situation that requires judgment (Haubl and Trifts 2000; Kasper 1996). In online webstores, vendors can easily offer highly interactive types of decision support. These co-called interactive decision aids (IDA) “help consumers in making informed purchase decisions amidst the vast availability of online product offerings” (Wang and Benbasat 2009, p. 3). However, the application of IDA is not restricted to purchase decisions. They are general enough to be of use in any kind of choice task where alternatives are known.
Simulation-based Evacuation Planning for Urban Areas
2021
Evacuation planning is a critical task in disaster management. Especially in situations such as natural disasters or terrorist attacks, large crowds need to move away from danger and reach designated safe zones. For this purpose, various approaches that efficiently compute evacuation plans in urban areas have been proposed. To evaluate the computed plans, previous works employ heuristics that can only roughly estimate the egress time of each plan. Intuitively, a much better approach is to estimate the egress time via simulation. However, designing a simulation model is usually a time-consuming task and, what is more, this model can only be used to evaluate evacuation plans for a specific ar…
Vitrification in assisted reproduction: myths, mistakes, disbeliefs and confusion
2009
The purpose of this work is to update embryologists and clinicians on different approaches in human oocyte and embryo cryopreservation, by clarifying some misunderstandings and explaining the underlying reasons for controversial opinions. The work is based on literature review and critical analysis of published papers or conference abstracts during the last 24 years, with special focus on the last 3 years. Due to the latest advancements in techniques, cryopreservation now offers new perspectives along with solutions to many demanding problems, and has developed from a backup procedure to a successful alternative that is an indispensable constituent of assisted reproductive techniques. Howev…
“Lições do mestre“: da tradução como viagem e da literatura como direito
2019
Combining critical perspectivation and personal account, I hope to offer a retrospective on my experience with the thought of Antonio Candido and a contribution to what we could consider his legacy. First I talk about my translation of a selection of his essays to German for an anthology published in 2005, about the translator’s readings and reflections, which serve as a starting point for rethinking some fundamental issues of Candido’s thought, such as the critical task of teaching and studying literature, also the question of literature’s social (ir)relevance in our days, as analyzed in the famous essay “O direito a literatura” (“The right to literature”, 1988).
Adicción a la pornografía: interferencia atencional y gravedad del consumo
2019
Introducción: El aumento del uso de las Tecnologías de la Información y la Comunicación (TICS) e Internet en nuestra sociedad ha potenciado la aparición de nuevas formas de adicción. Una de las más relevantes por sus implicaciones sociosanitarias sería la adicción al cibersexo, y más en concreto, el visionado excesivo de pornografía online. Numerosos estudios apuntan que, en determinadas personas, el visionado de pornografía puede sobrevenir excesivo e incontrolado, generando graves problemas en las diferentes áreas de la vida. Por ello, es importante explorar aquellos factores que actúan como predisponentes o mantenedores de este problema. Se postula que uno de ellos podría ser la capacida…
Theta and gamma oscillations in the rat hippocampus during attentive lever pressing
2018
AbstractThe hippocampus is known to be pivotal for spatial memory but emerging evidence suggests its contribution to temporal memories as well. However, it is not clear how the hippocampus represents time and how it synchronizes spatial and temporal presentations into a coherent memory. We assessed the specific role of hippocampal theta and gamma oscillations and their interaction in short-term timing of motor reactions. Rats were trained to maintain lever pressing for 2.5 s and then to quickly release the lever and retrieve water reward from a nearby water port guided by a cue light. In essence, this task allows observation of hippocampal rhythms during timed anticipation when no overt mov…
E-wave and heart rate responses during anticipation of nonmotor events.
1994
This study concentrated on three main questions: 1) can anticipatory late negative shift (expectancy wave, E-wave) be elicited in nonmotor S1-S2 paradigm, 2) is it sensitive to variation of emotional aspects of the task and 3) is there a connection between heart rate (HR) responses and E-wave. S1 was a letter row that was replaced tachistoscopically by another letter row (S2). The task of the subjects (n = 12) was to detect if the critical aspects of S2 were similar to S1. After their delayed response they received feedback of their performance. The emotional aspects of the task were varied by presenting aversive noise bursts at the end of the feedback period either always, contingently to …
The Role of Task Values in Adolescents' Educational Tracks: A Person-Oriented Approach
2009
The present study examined what kinds of patterns of task-values adolescents show, and whether these patterns predict their educational and occupational expectations and school track. Six hundred and fourteen adolescents were examined twice before their transition to secondary education and once thereafter. The clustering-by-cases analyses identified 6 groups: (1) those who placed a high value on all school subjects, (2) those who did not value any of the subjects, (3) those who valued Finnish and social sciences, (4) those who valued in particular practical and art subjects, (5) those who valued only practical and art subjects, and (6) those who especially valued mathematics and science. T…
East Asia in the Global Economy: Theoretical and Empirical Questions for Marxism
2019
As Marxism and socialism pass through watershed years it is important to reflect on the abiding questions of Marxist theory and empirical analysis. This article takes up this task in the context of East Asia under the impetus of globalisation and neo-liberalism, introducing a collection of five articles collected in the special issue. The article shows that questions Marx posed about the global economy more than a century ago remain prescient and continue to animate cutting-edge research, as shown in the articles in this special issue.
Reading literacy in Compulsory Secondary Education: an exploration of the difficulties in the use of information to answer questions / La competencia…
2014
AbstractThis paper is a review of studies about processes and secondary school students’ difficulties with these processes when they use information to answer questions. The PISA program uses this kind of task-oriented reading situation to evaluate reading literacy, which is also a common reading situation in educational settings. Four key strategies are identified to successfully perform this kind of task: decide how to read the information, comprehend the task, decide when to search for information in order to solve the task, and self-regulate that search process. Moreover, this paper provides accurate information about the students’ difficulties in becoming skilled readers when they use …
